An anti-seepage slurry material infiltration instrument for landfill

Abstract

The invention discloses an anti-seepage slurry infiltration instrument of a refuse landfill, and belongs to the field of environmental geotechnics. The anti-seepage slurry infiltration instrument comprises a reservoir, a cutting ring, a filter disc, a filtrate container, a side pressure pipe and a vent valve, wherein the lower part of the reservoir is opened, and the opening is hermetically connected with one end of the cutting ring, the other end of the cutting ring is connected with the filtrate container through the filter disc, and water drainage holes are formed in the filter disc, and the side pressure pipe and the vent valve are respectively arranged on the top of the reservoir. The infiltration instrument is simple in structure and convenient to operate, a test process is safe and reliable, a test result is accurate, and the anti-seepage slurry infiltration instrument used for the anti-seepage engineering of separation walls of various refuse landfills, the adsorption retardation of anti-seepage slurry is accurately tested, and the data support is provided for the anti-seepage quality of the refuse landfill separation wall.

Description

technical field [0001] The invention relates to a percolator, in particular to a percolator for anti-seepage slurry materials in landfills. Background technique [0002] With the acceleration of urbanization and the increase of urban population, a large amount of domestic waste will be produced. At present, sanitary landfill is the most commonly used treatment method for municipal solid waste in various countries in the world. Sanitary landfill is a garbage disposal method that uses anti-seepage, paving, compacting, and covering to treat municipal solid waste and treat gas, leachate, flies, etc. During the landfill process of municipal solid waste, leachate (or leachate) is formed due to the anaerobic decomposition of garbage microorganisms, leaching of precipitation, surface runoff and groundwater infiltration. The composition of the leachate is complex (NH 4 -N, TP, SS, COD Cr 、BOD 5 With high concentrations of heavy metals such as Hg and Pb), strong pollution, once l...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the shortcomings of the existing anti-seepage slurry material infiltration instrument, which is complex in field operation and unsatisfactory test effect, and provide a landfill anti-seepage slurry material infiltration instrument, which adopts the technical solution provided by the present invention , the structure of the percolator is simple, easy to operate, the test process is safe and reliable, and the test results are accurate. It is used in various types of landfill wall anti-seepage projects, and accurately tests the adsorption and retardation rate of anti-seepage slurry materials. Provide data support for the anti-seepage quality of the field separation wall
